Abstract: In one embodiment, a method for displaying a panoramic view image includes transmitting video data from a plurality of sensors to a data processor and using the processor to stitch the video data from respective ones of the sensors into a single panoramic image. A focus view of the image is defined and the panoramic image is scrolled such that the focus view is centered in the display. A high resolution camera is aimed along a line corresponding to a center of the focus view of the image and an image produced by the camera is stitched into the panoramic image. A mapping function is applied to the image data to compress the data and thereby reduce at least the horizontal resolution of the image in regions adjacent to the side edges thereof.

Abstract: Embodiments described herein related to devices and methods for the collection and/or determination of analytes, such as illicit substances including military explosives, explosives, and precursors thereof. In some cases, the device may be a disposable device that incorporates highly efficient sample collection in combination with microfluidic-based chemical analysis resulting in the rapid detection and identification of unknown materials. In some cases, multiple colorimetric detection chemistries may be employed, and the resulting “barcode” of color changes can be used to positively identify the presence and/or identity of the analyte.

Abstract: The current invention provides a modulated pressure wave vapor generator suitable for use outside of the laboratory. The vapor generator of the current invention produces a controlled analyte vapor sample without using bulk movement of gas. Additionally, the current invention compensates for changes in the environment to ensure discharge of the preferred volume of analyte from the vapor generator. Finally, the current invention provides a method for generating a controlled volume of analyte vapor suitable for calibrating vapor sensors.
